Filed: 1938-12-07
Abstract: 522,378. Coin-freed kinematograph apparatus. STERLING & MICHAELS, Ltd., and STERLING, H. Dec. 7, 1938. No. 35636. [Class 27] [Also in Groups XXXVIII and XX] A coin-freed device for controlling a sound and picture film apparatus is shown in Fig. 3. A coin or check is taken by a slide 14 over fraud-preventing gates 16 of known kind and dropped over the end 19 of a lever 20, which is thereby rocked to the dotted line position. In that position, a mercury switch 21 carried by the lever closes a circuit which sets the apparatus in operation The film in the apparatus is an endless one and has a side notch, which in a known way allows a spring controlled lever to close a switch when the operation is completed. The closing of this switch energizes an electromagnet 22, which returns the lever 20 to the normal or rest position shown in full lines in which the mercury switch is open.

Abstract: 1,080,212. Preheating furnace charges. ESCHER WYSS A.G. Sept. 15, 1964 [Nov. 4, 1963], No. 37632/64. Heading F4B. Pulverulent raw material is preheated before being fed to a rotary cement kiln 1 by a counter current waste gas stream from the kiln, the raw material being separated in a classifier 3 into coarse and fine fractions, the coarse fraction only undergoing open heat exchange with the gas in cyclones 8 and 7 inserted in the coarse fraction pipe-line 4, 5, 6. Fine fractions comprising 10 to 20% of the total are fed to the kiln 1 via pipe-line 2. The waste gas passes via lines 9, 10 and 11 through the cyclones 8, 7 and the classifier 3, along lines 12, 13 through dust arrester 14 and air exhauster 15 to chimney 16. Valves 17, 24 and 28 pass a portion of the gas flow in each of the sections 9, 10 and 11 to multicyclones 19, 26, 30 wherein the very fine dust which has the alkali compounds precipitated on it is separated from the waste gas stream before the latter passes on to the next heat exchange section, to prevent alkali compound build up in the cement making process. Cooled waste gas from line 20 is mixed with the hot waste gases at valves 21, 27, 31 just prior to this separation in order to obtain the optimum temperature conditions for the separation of the alkali compounds. The waste gas stream may by-pass the classifier 3 by means of valve 22.
